Linguistic diversity
SIL Ethnologue defines a "living language" as "one that has at least one speaker for whom it is their first language". The exact number of known living languages varies from 6,000 to 7,000, depending on the precision of one's definition of "language", and in particular, on how one defines the distinction between a "language" and a "dialect". As of 2026, Ethnologue cataloged 7,170 living human languages. The Ethnologue establishes linguistic groups based on studies of mutual intelligibility, and therefore often includes more categories than more conservative classifications. For example, the Danish language that most scholars consider a single language with several dialects is classified as two distinct languages (Danish and Jutish) by the Ethnologue.
